Interplus® 256


Interplus 256 is particularly useful in the maintenance of offshore structures and other aggressive environments, such as oil refineries, coastal structures, pulp and paper mills and bridges, where dry abrasive blasting is not possible. Ideal for use in conjunction with wet abrasive blasting or ultra high pressure water blasting, or as a patch primer for rusty surfaces in maintenance situations. For use on hot surfaces continuously running at up to 150°C and for corrosion protection under thermal insulation of carbon and stainless steel. Interplus 256 is not designed for continuous water immersion. It should be noted that Interplus 256 is not suitable for overcoating with thin films of alkyd, chlorinated rubber, vinyl or acrylic finishes.


This formulation represents second generation surface-tolerant technology. The product has both application and performance characteristics optimized for use over a wider temperature range.

Features and Benefits:

  • Approval from UK Department of Transport (Item No. 159).
  • A high performance industrial maintenance coating for use on a wide variety of surfaces including hand or power tool cleaned rusty steel.
  • Pigmented with aluminium and lamellar micaceous iron oxide for improved corrosion resistance.
